Soaking the pulverized P. japonicus in sodium bicarbonate solution, and then concentrating them to obtain P. japonicus powder; S3 .Soaking the Semen japonicus powder in step S2 in an ethanol solution; S4. Concentrating the soaking liquid under reduced pressure to obtain the Semen japonicus powder after soaking; S5. Adding the Semen japonicus powder after soaking to ethyl acetate for microwave extraction to obtain the first extract and The first liquid slag; S6. adding ethyl acetate to the first liquid slag for microwave extraction to obtain the second extract and the second liquid slag; S7. filtering the first extract and the second extract after mixing, and reducing the pressure of the filtrate Concentrate, recover the solvent from the extract to a paste; S8. add deionized water to dissolve, slowly add the obtained solution to the macroporous resin for purification, let it stand for 1 hour, and perform gradient elution with ethanol, then concentrate under reduced pressure, and dry in vacuo Bovine seed extract.

Description

technical field [0001] The invention relates to the field of extracting active ingredients from the seeds of the petunias, in particular to a preparation method of the extract of the seeds of the petunias. Background technique [0002] Morning glory belongs to the genus Petunias of the family Convolvulaceae, and is also known as Hei Chou, Bai Chou, Er Chou, Morning Glory, and Morning Glory. The colors of morning glory flowers are blue, crimson, peach red, purple, etc. There are also mixed colors, and the edges of petals change more. It is a common ornamental plant. The fruit is ovoid and can be used as medicine. The leaves of morning glory are three-lobed, heart-shaped at the base, and the flowers are white, purple-red or purple-blue, funnel-shaped, and the whole plant has coarse hairs. Split-leaf morning glory is an annual winding herbaceous vine, the whole plant is densely covered with coarse hairs. The top 5 shallow-lobed capsules are spherical, and the seeds are ovate ...
